'Commonwealth of Israel' in the Bible

Remember, then, that once upon a time you Gentiles in the flesh, who are called 'the Uncircumcision' by that so-called 'Circumcision' which is itself the product of human hands in the flesh ??12 remember you were in those days outside Christ, aliens to the commonwealth of Israel, and strangers to the covenants of the Promise, devoid of hope and God within the world.
